Bulletproof glass is composed of glass (or organic glass) a composite material and quality engineering plastic with a special processed, it is usually transparent materials, such as PVB/ polycarbonate thermoplastic plastics (general force explicit resin namely Lexan resin is also called LEXAN PC RESIN). The appearance and the transmitted light it with ordinary glassbehavior, for small arms fire to provide some protection. The PC thick plate can be 136 mm thick,maximum width up to 2166 mm wide, the effective time of 6664 days.Different manufacturers vary the bulletproof glass. But basically are in ordinary glass layerclamped polycarbonate material layer, a process called lamination. In this process, the formation of a similar to ordinary glass than ordinary glass thicker material. Polycarbonate is a hard transparent plastic -- people usually use it (Lexan brand, Tuffak or Cyrolon) to call it. Bullet proof glass with thickness of 7 mm to 75 mm. Shot in the bulletproof glass of bullets will penetrate the glass outer layer, but the polycarbonate glass material layer can absorb the bullet energy,thereby preventing it penetrates the glass. These chunks of bulletproof glass has been made useof in public during the second world war is usually thicker than 10 cm to 12 cm, and extremeweight.For example, some banks use bullet proof car to promote one-way bulletproof glass of the invention. Outside the small arms fire glass this glass will follow close on succession ofresistance, but will be allowed in the glass on the side (Li Ce) shooting, such as the defenderfrom the bullet proof car side in the shooting, which through the glass in the external threat onfire.

In bomb attacks and accidental explosion, direct harm anti bomb glass can minimize the explosive shock wave super high load and high speed flying glass fragmentation caused byreducing costs, repair facilities around attack facilities or the center of the explosion. Anti bombglass in the load increasing energy of explosion shock wave formation, increased severalfold even a few times to maintain conditions do not penetrate the glass, keep the value RET = 1.While the monolithic glass (including float glass, tempered glass, hollow glass) once broken, as long as slightly exceeds the critical breakdown pressure RET soon fell to below 0.3, glass fragments scattered, the emergence of penetrating damage. [1]

The explosion-proof function

In the global scope, bomb attacks (including car bombs, suicide bombers) and threats continue to rise, Marriott Indonesia is a typical event, with the increase of the bombs, the people's life safety and property have been very serious threat. According to security experts and relevant data shows, glass fragments scattered and the spatter is the main reason people get hurt. In the bomb terrorist bombings, 75% damage and glass related, this means that if the use of anti bombglass can reduce the injury degree of 75%. If the explosion happened, all the buildings in theglass can be completely retained in the frame, then the shock wave energy will not enter indoor,indoor items will not damage; damage of high speed fragments can not enter the buildings ordropped to the ground.

Frame system

The explosion of the rapid expansion of the shock and vibration is mainly caused by the damage of glass. Generated source fragments in weapon itself and the surrounding environment (such as shaking off buildings caused by debris), destructive effect to withstand bomb attacks, the firstglass must withstand the blast and fragmentation in the two aspects of the attack. Calculation of anti bomb glass and software through professional calculation of anti bomb glass frame system,can according to the glass retention, explosion shock pressure and shock wave pulse(kPa/msec), duration (MS msec), the extent of damage conditions were tested to calculate the bomb exploded when certain equivalent of the glass and the system can remain intact (glassunruptured) and rupture (cracks, there can be part of the debris fall off, has penetrated the).Anti should meet ASTM F1642-96 standard test requirements bomb glass.



Q:What is the content of the building safety glass management regulations?
Q:Is it double? Than the average after the glass?
Insulating glass: Hollow glass is composed of two layers of glass, surrounded by high strength, high air tightness composite adhesive glass and seal, glass bar adhesive seal, the middle of 6-9mm air layer filled with dry gas, With a desiccant to ensure the dryness of the air between the glass sheets. Figure. Its characteristics, due to leave a certain cavity, and has a relatively good insulation effect, so in the northern city has been widely used. In the sound insulation performance, the high-frequency noise (such as the voice of people talking, the school tweeter, etc.) in the insulating glass has good sound insulation effect, but the effect of low frequency noise (such as bus engine noise, train noise, aircraft noise, etc.) It is not obvious that the air cavity of the insulating glass resonates with the low frequency noise in the low frequency region (Note 1), and the low frequency noise is relatively easy to enter the room through the glass. Insulating glass production sub-machine line processing and manual processing of two, pipeline processing for large areas (ranging from thousands of square meters, more than 10,000 square meters) to use, manual processing is generally used for home users. Compared with the two processing methods, the quality of the product produced by the machine assembly line is relatively stable. The quality of the handmade product will be different because of the quality and process of each manufacturer. The hollow glass with poor quality will be over half a year or After a long time the internal fog and can not wash. So please pay attention to identify!
Q:Is the architectural glass look good?
Q:What is the introduction of new glass advertising slogan
New glass, all the way leading, to create a dream.
Q:Glass insulation film how to tear off
With a hair dryer while blowing side of the tear, this should be able to!
Q:I saw some of them in the high-rise buildings on the glass window posted a film, which can see outside, outside can not see inside, what is the film? Are you expensive?
Oh, ask them what paste the film chanting. A building are posted, and certainly have the effect will be such a ,,,,,
Q:Is the glass shading coefficient the shading coefficient?
No. The shading coefficient on the 2680-1994 can be understood as "the shading coefficient of the glass", and the so-called shading coefficient is divided into "integrated shading coefficient", "shading coefficient of glass" and "shading coefficient of outer shading measures", the first Equal to the last two products.
Q:I am a listed glass production enterprises in the clerk, mainly to do the Dalian area of the construction of the glass market, as just doing this business, some touch the mind, do not know how to finally let Party to own glass brand Finalists, in fact, know that this side and Party A, Design Institute, as well as curtain wall construction side has a close contact, but for how to cut is not very clear, hope you master maze.
Go to the site! Although the opportunity is slim, but do not take the first step how to run the relationship? Relationship is running out ah!
Q:VRAY rendering glass parameters how to tune?
The setting parameters for clear glass and ground glass are different. clear glass: Diffuse: Gray (light gray) Reflex: 255 Refraction 255 Refractive index 1.2 ~ 1.5 can be, generally 1.5; Matte glass: Diffuse: gray (light gray) Reflex: 255 High light: 0.6 ~ 0.8 are glossy (high light): 0.9 Refraction: 255 Gloss (fuzzy): 0.9 Refractive index: 1.2 ~ 1.5 can be, general 1.5 After setting, you can take a small picture to see the approximate effect, and fine-tune according to the ambient light source.
Q:Does anyone know of an automobile from the 1930's that had 2 large built in glass flower vases in the backseat on either side?
those types of cars in that year would be custom built/the chassis and cab from maybe cadillac and the body from custom builder/thomas edisons daughter had one and it is really beautiful/the "trunk" is a real trunk attached to a rear bumper/so no production car is available
